1- Mists of Pandaria. Marked the first time I cancelled my subscription. I didn't feel connected to the plot of the expansion, and more of it annoyed me than I enjoyed. I'm not a big raider, but I am an alt-oholic quest completionist so most of my opinions are based off that perspective and for me Mists of Pandaria resulted in the most underwhelming questing experience of the game. Although the music is excellent.

1. Warlords of Draenor. I'll start off by saying that actually Frostfire Ridge is one of my favourite zones in the game, I just didn't enjoy a single zone after that. Something just felt a bit off and it's the second time I've cancelled my subscription. I enjoyed the concept of the expansion at first, but it just felt a bit all over the place to me as it went on and being a poorly played rogue main I was about as tough as a kitten for the first patch and bit which didn't make it fun. A lot just seemed to focus on parts of the game that don't interest me. (Garrisons)

Tied 4. Burning Crusade. Nostalgia bonus points aside (it was when I started playing) BC had some of my favourite parts of the game and my second favourite endgame content (until I gave up raiding in cata). But it also has some of my absolute least favourite parts of the game. Kara? Nice. Intimidating demon onslaught when you first enter Outland? Nice. Absurdly mismatched gear while levelling? Nice. Hellfire peninsula? God no. A time before achievements (mostly)? Nooo. Being able to not afford flying above 60% speed because I was bad with money? Not fun.

Tied 4. Cataclysm. I feel like cata was an expansion with people like me in mind - people with all vanilla Azeroth quests completed and dusted and all hidden places scouted out getting treated to completely revamped quests and zones to level new characters through? Thanks blizzard (and not a sarcastic one!) I mean I dislike how polished the revamped zones felt and the lure of mystery hidden quests that could be somewhere died with the vanilla zones but some of the revamped Azeroth zones are now some of my favourites in the game when previously they'd felt a little dry. (Eg Westfall) although some definitely suffered (Hillsbrad :'( ). It's also had some of the most enjoyable and coherent feeling dailies and alternatives to raiding at max level. Although I will never enjoy dragon soul. But on the whole I enjoyed new Azeroth so much it put Cataclysm at a safe tied second for me.

1. Wrath of the Lich King I feel like putting it first on the list isn't really justifying how much more I enjoyed it than the other expansions. I mean I enjoyed most of the others, but I adored Wotlk. Nothing beats it for me in terms of story (it was a threat you'd been fighting arguably since level 1 depending on race), it was a story that flowed exceptionally well, as much as vehicle quest mechanics were horrific then it felt like they were trying new things - it felt fresh, it brought achievements (kind of - does a pre expansion patch really count?), it had an excellent pre expansion event (where I got my first ever epic), it has quite a few of my favourite dungeons and raids, it has a lot of my favourite music in the game, I even liked the design of the herbalism plants. I don't think I could possibly say enough good things about it. I mean Dalaran was a nightmare to play in at the time, but Dalaran itself has to still be the most fun city in the game. Plus in my degree I spend a lot of time studying the viking age and medieval Iceland, so although I hadn't started it back during wotlk it's fun to come back to play through the content now for its Norse influence. Also Howling Fjord is the best zone in the game.
